CRYSTAL STRUCTURE OF PSEUDOMONAS AERUGINOSA LECTIN 1 COMPLEXED WITH GALACTOSE AT 1.6 A RESOLUTION
OverviewOverview
The structure of the tetrameric Pseudomonas aeruginosa lectin I (PA-IL) in, complex with galactose and calcium was determined at 1.6 A resolution, and, the native protein was solved at 2.4 A resolution. Each monomer adopts a, beta-sandwich fold with ligand binding site at the apex. All galactose, hydroxyl groups, except O1, are involved in a hydrogen bond network with, the protein and O3 and O4 also participate in the co-ordination of the, calcium ion. The stereochemistry of calcium galactose binding is, reminiscent of that observed in some animal C-type lectins. The structure, of the complex provides a framework for future design of anti-bacterial, compounds.
